Tetradopterus Wing Shard

This jagged, iridescent shard appears to be a fragment of the wing of a Tetradopterus. When held, it grants the user the ability to mimic the natural agility and flight-like grace of the creature. While holding the shard, you gain a +1 bonus to Dexterity saving throws. Additionally, once per long rest, you can use an action to activate the shard to gain a glide effect, allowing you to descend up to 60 feet without taking fall damage, moving horizontally up to half the distance fallen.
